  table, div {font: 1.25em/1 Ahem;}

  table

  border: white solid;
  border-width: 0px 29px; /* horizontal table border width is 58px total */
  border-collapse: separate;
  border-spacing: 15px 4px; /* horizontal border-spacing width is 75px total */
  table-layout: fixed;
  width: 533px;

  /*
  "With this (fast) algorithm, the horizontal layout of
  the table does not depend on the contents of the cells;
  it only depends on the table's width, the width of
  the columns, and borders or cell spacing."

  So,

    533px : total table width
  -
     58px : total horizontal border width
  -
     75px : total horizontal border-spacing width
  ========
    400px : total to split among the 4 columns

  /*
  100% - (13% + 22% + 31%) == 34% for last column
